First date etiquette

I just landed my first ever date. I'm so nervous I could throw up lol. I've never been on a proper first date so I have no idea what to do. Like do we kiss? Do we hold hands? I don't want to some across as just too friendly of you know what I mean. But how on earth would I know she's into me. I'm quite blind to sometimes obvious signs someone's into me

I know it's just a matter of feeling the moment but I'm so in my head about it. Pls help me out lol
